I am not sure why TESCO, a UK based company, is trying so hard to cut into the South Korean market. Wal-Mart Korea was competed out by E-Mart in 2006. Whatever the reason, they sure are giving their competition a run for their money.

This is possible only because South Korea has the infrastructure already built in where every underground subway is laden with phone and free wifi signals. American cities have far outdated infrastructure and shortage of funding. I doubt this will happen in our subway stations any time soon. But I do see a possibility for bus stations.
